DescriptionRFX Pro Series Elite Aluminium - 520 Sprocket

Product details :

Features

The RFX Pro Series Elite aluminum 7075 sprocket (manufacturer part number: FXRS 40-49 99BK) is designed for demanding riders seeking a lightweight and durable component for their motocross or roadster machines. CNC machined and anodized black, it features a racing look while being engineered for off-road use thanks to its mud evacuation grooves that facilitate maintenance and extend the lifespan of the chain and sprocket.

Main Features:

Color: Anodized black
Material: Aluminum 7075, CNC machined
Number of teeth: 49
Chain pitch: 520
Type: Standard
Laser-etched RFX logo
CAD-designed profile to optimize lightweight
Mud evacuation grooves and color coding by model

Its rigid design and tight tolerances contribute to better performance under load and a more precise interaction with the chain. Ideal for renewing a final drive or giving an aesthetic refresh to the motorcycle, this sprocket fits applications with a 520 pitch and is particularly suitable for SUZUKI RM-Z 450 (2026), RM-Z 250 (2026), and RMX 450 (2019).
